MANURE-SBREADER.

Specification of Letters Patent.

Patented July 30, 1912.

To all whom it may concern Be it known that I, HowARo F. SNYDER, a citizen of the United States, residing at Newton, in the county of Jasper and State of Iowa, have invented a certain new and useful lVIanure-Spreader, of which the following is a specification.

The objects of my invention are to provide a manure spreader to be used in connection with the running gear of the ordinary farm wagon and so constructed and arranged that its body will take the place of the ordinary wagon box and it. is so arranged that the operative portions of it are driven by the rear wheels of the wagon.

A further object is to provide a driving mechanism for the apron of the spreader which together with the heater are controlled in their operation by a single lever designed to be manually operated by the driver from a position near the forward end of the body of the spreader.

A further object is to provide a mechanism operatively connected with the lever near the forward end of the body by which the speed of the apron is controlled.

A further object is to provide a mechanism for rolling up the apron at the rear end of and below the floor of the body which is operated largely by the downward movement of the apron.

A further object is to provide a manually operated mechanism for returning'the apron to its normal position in'the body.

A further objectis to provide rigidly braced supporting plates at the rear end of the body designed to prevent the operative parts of the device from getting! out of re pair.

A further object is to provide a beater designed to force the manure in the argon over it in small quantities to a point of discharge.

A further object is to provide a mechanism by which the spreader can be easily and detacbably secured to the wagon frame.

.\l v invention consists in the "onstrucliou. :u'ran reuicnt and combination of the vari ous parts of the device. whereby th obiccb contemplated are attained. a lu'rcinal'tm' more fully set forth. point d out in my claims and illustrated for the acco|n mu\'- inn drawings. in which Figure l is a side elevation of the left side of a wagon with my spreader mounted on it after the box has been removed. Fig. 2 is a plan view of the forward end of the apron and upri ht plate connected to its forward end and also the crank mechanism for drawing it forwardly. Fig. 3 is a. detail view of the cam actuatwl lever which is preferably'on the right side of the machine designed to drive the shaft which operates the apron. Fig. 4 is a detail view of the operating lever for throwing: the beater into and out of gear. Fig. 5 is a detail view of the cam and its attachments for operating the cam actuated lever. lookinp at it. from the inside.

Fig. 6 is a sectional view of the mechanism shown in Fig. 5. Fig. 7 is a rear elevation of my spreader. Fig. is is a longitudinal, sectional view of the rear portion of the spreader. l ig. 9 is a detail view of the spring which is connected to the shaft upon which the apron is wound. Fig. 10 is a side elevation of a rear end of the right. side of my spreader. Fig. it is a side clevation of the rear end of my spreader loot; ing at the left side of it with the sprocket chain removed and the rear wagon .vheel removed, and Fig. 12 is a detail view of the upper end of one of the wagon stays to which my spreader is secured by In ans of a fastening device.

Referring to the accompanying drawings. I have used the reference nunieral it) to indicate the forward wheels of a wagon. and the luunerals 11 and 12 to indi ate the two rear wheels. 'lhese wheels are connwted y the ordinary reach 13 and at the for wartl end and extending upwardly from the torward truclt are the usual s ays l l. Extending upwardly from the rear truclv and on each side of it are the usual stavs 15'". The agon box used with the truck ha been rc moved and my spreader pla ed in position on the trucks in place there f. This spreader is constructed in the foll wing manner: The body of the spreader con ists f a bottom l3. two sides l? and i7 and the front portion l (muted on the bott m lI i an apr n uunprising llu' -proclt l chain 1! and it! whi h are onnect d v a wrio ol' t'l't-. bars ll. as shown learly in Fig. L. The l u'ward bar of tlii. scrim of cross bars. which f r the pin-pow of coir \cnicnre l have numbered 312. has atta hed to it two chains 23 and 24. which are set liv'hllv inside of the end of the l or and out f line with the sprocket chains. In and 2d ltltl and are thus arranged to prevent the sprocket wheels which drive the sprocket chains 19 and 20 from further advancing the apron when the ends of these chains 19 and 20 have been reached. as will be more fully set out hereinafter. Attached to the forward ends of these chains 23 and 24 is an upright plate 25 having an angular extension 26 designed to rest upon the bottom 15 of the body and to slide over said bottom when the apron is moved toward the rear or the forward end of the box. I have provided braces 27 between the rear of the upright plate and the angular extension 26 for supporting the upright plate 25 in its upright position.

Rotatably mounted and secured to the forward end 18 of the wagon body is a windlass 26 to which is secured at one end a rope 29, and at its other end this rope is secured to the central forward portion of the upright plate 25, so that as the Windlass is turned in one direction, the rope will be wound upon it and the apron will be drawn toward the front of the body. it is by this Windlass 28 that the apron is returned. after the spreader has delivered its load. Secured to the side 17 of the body and adjacent to its forward end is a notched sector 30 having pivoted to its lower portion a lever 31. capable of being moved forwardly or rearwardly. Secured to the lever 31 is an ordinary hand latch 32, the lower end of which is designed to enter the notches in the notched sector 30 and to maintain said lever in various positions throughoutits limit of movement, the purposes of this lever appear hereinafter. Adjacent to the rear end of the wagon body and secured to the sides 16 and 17 respectively are the posts 33 and 34-. each extending from a point somewhat abovethc top if the sides to a point co1--'-.irl-ialily below the sides.

Extending longitudinally of the sides 16 and 17 and near their rear ends are the shell... .15 and 36. which are rigidly braced by the braces 37 and 38 respectlvely. as clearly shown in Fig. 7. These shelves are designed to support certain parts of the 0perative mechanism and to prevent foreign substances ele ated by the wheels 11 and 12 from getting into these operative mechanisms and clogging them. I have provided a metal plate 39 which is secured to the post 34 and the shelf 36 by bolts passing through angular extensions of this plate 39. The forward end of the shelf 36 is supported by means of the angle iron 40. The lower end of this angle iron 40 supports a hearing 41 for a sprocket wheel 42 which adjustably supports the forward end of one of the driving sprocket chains. This bearing is made adjustable by means of a screw 43 entering the bearing support 44 and the lower forward end of the angle iron 40. I also iron 51.

provide a metal plate 45 which is secured to the post 33 and the shelf 35 by bolts passing through angular extensions of this plate 45. The forward end of this shelf 35 is rigidly supported relative to the side 16 by means driving chains on this side of the machine.

This bearing is made adjustable by means of a 'screw 49 entering the bearing support 50 and the lower forward end of the angle iron 46.

Secured to the forward side of the post 34 0 and the top of the shelf 36 is a slotted angle In the slot of this angle iron 51, I have placed a fastening bolt 52 having a right angled extension 53 at its lower end.

This right angled extension 53 is designed 35 to enter an opening 54 at the upper end of one of the wagon stays 15 and the nut 55' on the upper end of the bolt 52 is then screwed up to securely hold the body of the spreader in position relative to the trucks.

The forward end of the right angled extension 53 is turned up at 56 to prevent its.

slipping out of the opening 54 and thus ob viate any danger of the spreader slipping from the trucks. 51 is designed to allow the bolt to move forwardly and rearwardly so to ada t my spreader for wagons var ing somew at in length. The opposite si e of the body is held in position relative to the other stay 15 by means of a similar slotted angle llOIl which. I have designated by the numeral 57 and a bolt 58 having the ri ht-angled extension 59 and the upturne forward end 60 and the nut 61, all of which are similar in all respects to the similar parts on the bolt 52.

I have provided two driving sprocket wheels 62, one of which is designed to be detachably connected with the wheel 11 and the other of which is to be detachably connected with the wheel 12, as shown clearly in Fig. 1 of the drawings. Connecting the upper ends of the posts 33 and 34 is a retaining rack comprising the shaft 63 and! the tines 64 designed to prevent the manure from being forced over the heater in large quantities as said heater is o erated. Extending across the rear end 0 the spreader and connecting the metal portions of the 2 rear central portions of the plates 39 and 45 is a shaft 65 having its left end 66 squared. On this shaft 65, I have mounted a cylinder comprising two plates 67 and 68,

said plates being connected by a cylindrical beater 69. Mounted on the shat 65 immediately outside of the plate 39 is a sprocket wheel 70 with; a ratchet faced shoulder 71 on its outer side. Slidingl mounted outside of the ratchet faced shou 139 The slot in the angle iron 95 the ratchet face of the collar t 1hr 73 is a ratchet faced collar 72 having an annular groove 73 encircling'it. This collar 72 slidingly mounted on the flttltlltftl end 66 of the shaft. 65 and when "2 ire held in engagement with the ratchet face of the shoulder 71 and the sprocket wheel 70 is driven, the beater will be operated to drive material over it.

Pivotally attached to the underside of the shelf 36 is an operating lover. The operating" lcv comprises an angular rod 74 having a downwardly extending member 75 com'iected with its rear end and having its lower end bifurcated to form the engaging members 76 and 77 which enter the annular groove 73 in the sliding collar 72 in such a way that as the lower end of the downwardly extending member 75 of the operatin g lever is moved outwardly and inardly. the collar will he moved in a corre' sponding direction and yet at the same time, the collar will he allowed to rotate while the engaging lncn'ibers are in the annular groove. In the forward inner end of the operating lever, 'I have provided an opening 7?? through which a chain 79 is attached.

This chain is also attached at its lower end to the arm so of a hell-crank lever 81 which [S secured to a shaft 82. The other arm 8?) of tho hell crank lever St is pivotally at tached to a rod %4 connected with the lower end of the lever ill at the forward side of the machine. that when the lever 31 is drawn to its extreme forward limit of move incur, the ratchet-faced collar 72 will be thrown not of engagement with the ratchet taccd shoulder 71 and the heater will be thrown out of operation.

I have providcd a H'fi'illg 85 which atla hcd to the do\vnw:n'dl extending memhcr T3 of the operating lcvcr and also atta hc i it: e outside of the plate ll) so as to norma ly liold the ower end of the memher 75 toward it inner lim of movement and the h ater in cjcar.

The ahat't 8: ahovc referred to, is

mounted in the posts 33 and 34 and extends across'the rear end of the machine. Securely attached to the right end ofthe shaft 82 is a crank arm 92 having an opening in its lower end through which the chain 93 is secured to they lower end of the arm 92. Extending across the rear end of the spreader and immediately beneath the bottom of it, is a shaft 94 on which is mounted two sprocket wheels 95, over which pass the sprocket chains 19 and of the apron. Rotatably mounted between the plates 39 and and below the shaft 94 is a shaft 96 which has a sprocket wheel 97, at each end of it to which are secured the rear ends of the sprocket. chains 19 and 20 of the apron. There is a spring 98 secured to the shaft 96 and to the plate 43 which assists in winding the pron around the shaft 96 as it is advanced rearwardly. As the shaft 94 is driven, the apron is moved rearwardly and its weight as it passes over the shaft 94 and down one side of the shaft 96 tends to largely rotate the said shaft 96 and with the assistance of a spring 95, this winding operation is completely performed. The spring 98 is wound up as the apron is drawn forwardly hy means of the windlass 2S.

Secured hctwecn the plates and 45, I have provideda curved plate 9%) beneath the forward portion of the cylindrical heater to prevent foreign substances from getting into the apron as it is being wound around the shaft 96. Mounted on the right end of the shaft 94 is a ratchet 100 having the retaining pawl 10], which is pivotally secured to the post. 31), in engagement with the rat het and is designed to prcvcnt its rotating in one direction.

Pivoted on the sha'lt 94 and immediately inside of the ratchet 100 is a driving arm 102, which is connected with the arm 92 by means of the chain 53, ahove rcl'crrcd to, so that as the arm 92 moved forwardly at its lower end. the driving, arm 102 will also he moved in the same direction. This driving arm ha a roller 103i mounted at itsoutcr end and at suhstantiallv right angles to its hody portion. l\'lountcd on the arm W2 is a driving pawl lUl havina the spring 103 con ncctcd with it and with thc arm for n1aintaining this pawl in driving engagement with the ratchet loo so that as the driving arm is moved forwardly a m-rtain distance, the ratchet Hit), the .shaft A l and its attachments are. driven a certain prcdctcrmincd distance; I have providcd a coil spring 106 secured to the outside oi the plate l5 and the driving arm 10; hr maintaining its lower end at its rear limit ol' movement which is on r lled through thc arm 92 and it; illlilt'llllltllls hy tho h-vm- 2;],

llolatahly mounted on the outer cud i the shaft it; is a Slllfltlfll \vhccl it)? having mounted inuncdiatcly imidc of it and secured to it an internal gear 108. Mounted beside the internal gear 108 is a cam 109. Connected with the cam is a pawl bearing member 110 having the pawls 111 and 112 secured to its ends and pressed outwardly, by the springs 113 and 114 res ectively, into engagement with the teeth 0 the internal gear 110 so that as the sprocket wheel is driven in the direction of the arrow, shown in Fig. 10, (which is the normal direction when the wagon is being moved forwardly), the cam will be driven on account of the engagement of the pawls 111 and 112 with the teeth of the internal gear 108. When, however, the ratchet is driven in the opposite direction by the backing of the vehole, the ratchet will slide over the teeth of the internal gear and the cam will remain stationary. I have provided a sprocket idler 115 on the post 33. Passing around the sprockets 107 and 115 and 48 and having its under surface constantl in engagement with the wheel 62 on the right side of the machine is a sprocket chain 116 so arranged that as the vehicle is advanced forwardly, the gear 107 and its attachments will be driven in the same direction. As the cam 109 is rotated in the manner above referred to, it will engage the roller 103 on the driving arm and will consequently cause the ratchet wheel to be driven a certain distance and will hence cause the apron to be moved rearwardly a certain distance. The distance through which the apron is driven is determined by the length of the stroke of the driving arm as it is forced f ardly by the cam and as the driving agin is controlled by the lever 31, the length of the stroke of the driving arm can be regulated from the lever 31. When the lever 31 is moved forwardly to its extreme limit of movement, the cam will not enga e the roller 103 and hence the apron will thrown entirely out of operation as well as the beater.

In practical operation, the use of a single lever for accomplishing the three results is very advantageous as well as the constructing of the arts, as herein set out. The securing of t e device through the trucks of an ordinary wagon and the protection of the operative parts also effect a very advanta eous result and assist very materially in ma ing the construction permanently operative.
